Blade Right Raise Solenoid connections
This diagnostic code is associated with the blade right raise solenoid. The FMI 03 means that the ECM has determined that the voltage of the solenoid circuit is above normal.The ECM provides a PWM signal in order to control the solenoid. The ECM will vary the electrical current of the PWM output signal in order to provide proportional control of the solenoid.Some possible causes of the diagnostic code are listed:
The energize circuit of the solenoid is shorted to shorted to another voltage source.
The ECM has failed. This is unlikely.Before performing this procedure, inspect the harness connectors that are involved in the circuit. Poor connections can often be the cause of a problem in an electrical circuit. Verify that all connections in the circuit are clean, secure and in good condition. If a problem with a connection is found, correct the problem and verify that this diagnostic code is active before performing this procedure. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected.Note: The resistance of the solenoid coil should be 8.7 .4 ohms at 25 °C (77.0 °F).Test Step 1. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT
Turn the key start switch and the disconnect switch to the OFF position.
Disconnect the machine harness connector from the solenoid. Disconnect the machine harness connectors J1 and J2 from the ECM.
At the machine harness ECM connector J1, measure the resistance from contact J1-59 (wire R902-GN(Green)) to all J1 and J2 contacts that are used on the ECM connectors. Expected Result:Each resistance measurement is greater than 5000 ohms. Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 2.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between wire R902-GN(Green) and the circuit that has a low resistance measurement. Repair: Repair the machine harness or replace the machine harness.STOPTest Step 2. CHECK THE OPERATION OF THE ECMThe disconnect switch and the key start switch remain in the OFF position. The machine harness connectors for the solenoid and the ECM remain disconnected.
At the machine harness connector J1 for the ECM, use a 151-6320 Removal Tool to remove the solenoid energize wire R902-GN(Green) and socket at contact J1-59 from the harness connector.
Reconnect the machine harness J1 and J2 connectors to the ECM.
Turn the disconnect switch and the key start switch to the ON position.
Observe the status of the active CID 2161 FMI 03 diagnostic code. Expected Result:The CID 2161 FMI 03 diagnostic code is no longer active. A CID 2161 FMI 05 diagnostic code is now active.Results:
YES - The CID 2161 FMI 03 diagnostic code is no longer active. A CID 2161 FMI 05 diagnostic code has been activated after the solenoid energize circuit was disconnected. The ECM has responded correctly to the
